[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production planning expert system, and more particularly, to a construction method and construction apparatus thereof.

[0002]

2. Description of the Related Art In the conventional construction of a planned expert system, a human has coded a function for describing a constraint condition.

[0003]

In the conventional description of the constraint condition in the planning type expert system, since the function has to be directly coded, it takes a lot of time to create the function, and the maintenance and the person in charge of the operation accompanying the change of the constraint condition. However, there was a problem that it was difficult to create by itself.

It is an object of the present invention to provide a method and an apparatus for constructing a production planning expert system which automatically codes a function for describing a constraint condition by a constraint condition function basic pattern.

[0005]

According to the method for constructing a production planning expert system of the present invention, a target of a constraint condition and its attribute are input according to a preset editor for input conforming to the transfer of the constraint condition. , The constraint condition function basic pattern corresponding to the editor is transcribed, and the input information is automatically transcribed to the transcribed constraint condition function basic pattern.

Further, the production planning expert system construction apparatus of the present invention is, in the apparatus for constructing the production planning expert system, preset information for inputting the capability of each production facility, regarding the capability of each production facility. Means for inputting according to an editor, means for holding a preset constraint condition function basic pattern corresponding to the editor, and transcription of a constraint condition function basic pattern corresponding to the editor, according to the editor according to the editor And a constraint condition automatic coding unit including means for automatically transcribing input information.

Further, the construction apparatus for the production planning expert system includes one in which the means for automatically transposing the input information of the constraint condition automatic coding section includes a routine for generating a constraint condition function.

[0008]

Function: A constraint condition function corresponding to the editor, in which information on the capability of the production facility is input according to an editor set for inputting the capability of the production facility, and constraint conditions are preset based on the information. In the basic pattern of
Since it is described by a predetermined routine, the constraint function is automatically coded.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of a constraint condition automatic coding section of a construction apparatus for a production planning expert system according to the present invention, to which an embodiment of a construction method for a production planning expert system according to the present invention is applied. It is a figure which shows a part of image of the information input by the editor 1 shown in FIG.

The constraint condition automatic coding unit of the construction apparatus for the production planning expert system includes an editor 1,
Constraint function basic pattern 2, constraint function generation routine 3, constraint function file 4, memory (not shown)
Consists of. The editor 1 is a preset editor for inputting the capacity of production equipment. The constraint condition function basic pattern 2 is one of the basic pattern tables and is a basic pattern corresponding to the editor 1. Further, the constraint condition function production routine 3 calls the basic pattern 2 corresponding to the editor 1 used to store the information on the constraint condition to be input, and the basic pattern 2 input by the editor 1 on the basic pattern, for example, as shown in FIG. Enter constraints such as the maximum production capacity for each production facility and the time required for setup change as shown in.

Next, the operation of the automatic constraint condition coding section will be described.

First, an editor 1 suitable for constructing the production planning expert system is set, and information regarding the required capacity of each production facility is input by the editor. When the input by the editor 1 is completed, the constraint condition function generation routine 3 is activated to generate the constraint condition function from the contents input by the editor 1.

The generation method is as follows. First,
The basic pattern function corresponding to the editor 1 is called from among the basic patterns having the basic patterns 2 of the constraint condition function. If the input is made by the editor 1 for inputting the capacity of the production equipment, the function that is the basic pattern of the constraint condition regarding the capacity of the production equipment is called (step 31).

Next, the data input by the editor 1 is described in the basic pattern function called in the process of step 31 (step 32).

The details of this process will be described below with reference to an example of the capacity of the production facility. (1) The basic pattern function is transferred by the number of facilities input by the editor 1. (2) The value input by the editor 1 is transferred to the argument for searching the capacity of each facility. That is, the maximum production capacity and the time required for setup change are incorporated into the constraint condition function.

Finally, the constraint condition function created in the process of step 32 is output to the file 4 (step 3
3).

FIG. 2 is an image diagram of information input according to the editor 1 for simply inputting constraint conditions.
Here, it is an example in which the capacity of the production facility is input.

In this example, the production equipment is set vertically and the maximum production capacity and the time required for setup change are set horizontally. In this way, the objects of the constraint conditions are arranged vertically and the attributes of the objects are arranged horizontally. It is an editor 1 that creates such an image. Since the value of the constraint condition is the intersection of both, in the example of FIG. 2, the facility 1 is the target of the constraint condition, and the maximum daily production capacity is its attribute.
00 is the value of the constraint condition.

By adopting such an editor format, the basic pattern is transcribed by the number n of objects of the constraint condition, and the attribute value is input to the facilities 1 to n that are arguments. , Constraint condition function generation routine performs constraint condition automatic coding.

[0021]

As described above, according to the present invention, the description of the constraint conditions in the production planning expert system can be completed only by the simple input by the editor.
This has the effect that system development and maintenance can be performed easily, and the contents of the constraint conditions can be easily changed by the person in charge of business.
